Kaloula Borealis
The boreal digging frog (''Kaloula borealis'') is a species of microhylid, or "narrow-mouthed," frog found in Northeast Asia. Its range covers much of central and northeastern China, the Korean Peninsula Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic o ..., and Jeju Island. Adult boreal digging frogs are roughly 4.5 cm in length, round in shape with toad-like speckled skin. Tadpoles are up to in length. The boreal digging frog is common across much of its range, but is listed as an "Endangered category II species" in South Korea. It inhabits cultivated fields, including rice paddies, and is often found in close proximity to humanity, at altitudes of 10 to 900 m. Boreal digging frogs breed during the annual East Asian monsoon, rainy season, around June and July. After the rai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microhylid
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family (biology), family of frogs. The 683 species are in 63 genera and 11 subfamilies, which is the largest number of genera of any frog family. Evolution A molecular phylogenetic study by van der Meijden, et al. (2007) has estimated the initial internal divergence of the family Microhylidae to have taken place about 66 million years ago, or immediately after the Cretaceous extinction event. The most recent common ancestor of the Microhylidae and their closest Ranoidea, ranoid relatives is estimated to have lived 116 million years ago in Gondwana. Description As suggested by their name, microhylids are mostly small frogs. Many species are below in length, although some species are as large as . They can be arboreal or terrestrial, and some even live close to water. The ground-dwellers are often found under leaf litter within forests, occasionally venturing out at night to hunt.

Northeast Asia
Northeast Asia or Northeastern Asia is a geographical subregion of Asia; its northeastern landmass and islands are bounded by the Pacific Ocean. The term Northeast Asia was popularized during the 1930s by American historian and political scientist Robert Kerner. Under Kerner's definition, "Northeast Asia" included the Mongolian Plateau, the Northeast China Plain, the Korean Peninsula, the Japanese archipelago, and the mountainous regions of the Russian Far East, stretching from the Lena River in the west to the Pacific Ocean in the east. Definitions The definition of Northeast Asia is not static but often changes according to the context in which it is discussed. In common usage, the term Northeast Asia typically refers to a region which includes Northeast China (Inner Mongolia and Manchuria). Other countries and territories which make up Northeast Asia are the Russian Far East including the Sea of Okhotsk, Mongolia, Japan, North Korea, and South Korea. Parts or the whole of N ...

Korean Peninsula
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to civi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Rice Paddies
A paddy field is a flooded field of arable land used for growing semiaquatic crops, most notably rice and taro. It originates from the Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with pre-Austronesian and Hmong-Mien cultures. It was spread in prehistoric times by the expansion of Austronesian peoples to Island Southeast Asia, Southeast Asia including Northeastern India, Madagascar, Melanesia, Micronesia, and Polynesia. The technology was also acquired by other cultures in mainland Asia for rice farming, spreading to East Asia, Mainland Southeast Asia, and South Asia. Fields can be built into steep hillsides as terraces or adjacent to depressed or steeply sloped features such as rivers or marshes. They require a great deal of labor and materials to create and need large quantities of water for irrigation. Oxen and water buffalo, adapted for life in wetlands, are important working animals used extensively in paddy field farm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Asian Monsoon
The East Asian Monsoon is a monsoonal flow that carries moist air from the Indian Ocean and Pacific Ocean to East Asia. It affects approximately one-third of the global population, influencing the climate of Japan, the Korean Peninsula, Taiwan, China, the Philippines and Mainland Southeast Asia but most significantly Vietnam. It is driven by temperature differences between the East Asian continent and the Pacific Ocean. The East Asian monsoon is divided into a warm and wet summer monsoon and a cold and dry winter monsoon. This cold and dry winter monsoon is responsible for the aeolian dust deposition and pedogenesis that resulted in the creation of the Loess Plateau. The monsoon influences weather patterns as far north as Siberia, causing wet summers that contrast with the cold and dry winters caused by the Siberian High, which counterbalances the monsoon's effect on northerly latitudes. In most years, the monsoonal flow shifts in a very predictable pattern, with winds being south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaloula
''Kaloula'' is a genus of microhylid frogs found in southern and eastern Asia. They are sometimes known as the Asian narrowmouth toads. Species The genus currently has at least 19 species. Some sources also recognize ''Kaloula macrocephala'' Bourret, 1942 as a valid species, whereas the Amphibian Species of the World treats it as a synonym of ''Kaloula pulchra''. 5 new species have been described since 2000, and there are unnamed species yet to be described. ''Kaloula pulchra'', ''Kaloula picta'', and ''Kaloula borealis'' are the most widespread and commonly found varieties, often living near human settlements. Blackburn, et al. (2013) lists several ''Kaloula'' varieties that are likely to be new, previously undescribed species. *''Kaloula sp. nov. Palawan'': Closely related to ''Kaloula baleata''. Recorded in Palawan. *''Kaloula sp. nov. Sulawesi'': Closely related to ''Kaloula baleata''. Recorded in the Togian Islands (Batudaka Island), Central Sulawesi, and North Sulawesi ...

Amphibians Of Korea
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...
